An October 2016 Pacificon Presentation, Another Look at Transmission Lines which is a sort of summary of the SWTL technology, demonstrations and other activities on these pages. Please note that this is NOT "G-Line" as described by Goubau (which required slowing the wave down) nor is it the same as what Tesla described.

2nd Demo -100 meter SWTL - transmission/recovery of 144 MHz power guided along a single .013" (0.32 mm) conductor transmission line (SWTL) at 144.5 MHz using very light weight launchers. This system can be used to power quadcopters/aerostats for continuous flight while providing extremely low loss connection to elevated antennas - enabling quickly deployable, long range, very high bandwidth communications systems for Internet, emergency and other communications.

Pacificon 2011 Antenna Forum, I gave a presentation includes an overview of three different amateur applications for surface wave transmission line, along with a new antenna theory for understanding conventional antennas such as dipoles and monopoles as surface wave devices. All but the first of these, "A Flying Antenna" have been published as a three part series in ARRL QEX.

A Flying Antenna (published only on YouTube) a helium balloon supported, very broadband antenna made from paper producing 40+ dB gain),

Figure 4D, left axis, label for SWR should go from 1 - 10 rather than 0 - 10 as was published. The right axis gives return loss in dB as an independent plot sharing a common frequency (X) axis.

The Flying Antenna has not been published, due at least in part to the liability involved in providing construction and fabrication details of a
system which is potentially dangerous or even lethal. In order to not totally lose the value of that first section, Here is a YouTube video which broadly describes the antenna and experiment and gives a demonstration of surface wave transmission line in operation.

Here's the video of the Flying Antenna

with some additions detailing ways to improve higher speed amateur

those who otherwise would be unable to see it.
